This was posted to the 2015 blog, but the video interview of Dr. Rosedale by Dr. Mercola was taken off YouTube. Here's the content of the original post again:
HDL and LDL Are Not Cholesterol
We've all heard about how HDL is the good kind of cholesterol and LDL is the bad cholesterol, and people with "high" cholesterol need to raise HDL and lower LDL. Well, from this short interview with Dr. Ron Rosedale, we learn that HDL and LDL are not even cholesterol -- they are PROTEINS that transport cholesterol to and from the cells. (FYI: Proteins are used by the body to rebuild the cells and also as "taxicab" transporters of substances in the bloodstream.) HDL and LDL stand for high-density and low-density lipoprotein -- i.e., not a fat but a kind of protein). Cholesterol is itself an important precursor rebuilding/repair molecule manufactured in the liver, essential in the making of new cells and actually recycled when it is carried back in its "used" form from the cells.
Why doctors believe HDL and LDL are actually cholesterol is surprising. Additionally, doctors think that because LDL takes cholesterol TO the cells it is BAD, and because HDL takes cholesterol AWAY from the cells it is GOOD! Thus the medical community actually seeks to lower and raise LDL and HDL with pharmaceutical drugs, which only impairs the body's efforts to repair and heal the cells. A person with high LDL is someone whose cells need cholesterol for repair and rebuilding purposes, so lowering the number of cholesterol transporter cells (LDL) would only limit this!
